Description

OBJECT
Meissa /ˈmaɪsə/, designated Lambda Orionis (λ Orionis, abbreviated Lambda Ori, λ Ori) is a star in the constellation of Orion. It is a multiple star approximately 1,300 ly away with a combined apparent magnitude of 3.33.[11] The main components are an O8 giant star and a B-class main sequence star, separated by about 4″. Despite Meissa being more luminous and only slightly further away than Rigel, it appears 3 magnitudes dimmer at visual wavelengths, with much of its radiation emitted in the ultraviolet due to its high temperature.

PROCESSING
Normally when I create SHO images I try and resemble more blues, golds, and reds. However, this time around I left the SHO as NASA normally does except I pulled the magenta from the stars. The most important part of the process is I used NarrowbandNormalization to help accentuate the Oiii and Sii by boosting them as most people have never seen the Oiii as it's very small and next to the star 39 λ Ori Heka and looks like a small crescent moon.

I hope you enjoy it.
